[GPS and Maps] Need some things cleared up
I got a hold of the iphone and tested its gps. I loaded the map when I was on a wifi network, put in my destination and went for a test drive. Once I was at a location that the map needs to load, all I got was black and white lines. No picture what so ever. So, does this means that I need a data plan to fully use gps? If so, this sucks. What if I'm at a location where edge/3g reception is slow or don't exsist? I'll be lost! Why not build in the maps like Nokia or other phones? Any way around this?
